Show HN: EZ-TRAK Satellite Hand Tracking Suite

https://github.com/benb0jangles/EzTrak
41•benbojangles•9mo ago
EZ-TRAK is a comprehensive satellite tracking suite designed for amateur radio operators, weather satellite enthusiasts, and educational purposes. The software interfaces with an EZ-TRAK BLE device which is mounted to a lightweight foldable portable satellite dish antenna to hand track satellites in real-time, providing azimuth and elevation data for optimal antenna positioning.

When you say "hand track", you're not kidding.

I was expecting something with motors controlled by a person, but this is literally picking up the dish and pointing it by muscle power.

Back of envelope, a 1 meter parabolic antenna at 1.7 GHz gives about 12 degree beam width (FWHM), which is what makes this practical. Very clever.

wkat4242•9mo ago
Really cool project! What kind of foldable dish do you use?
benbojangles•9mo ago
it's called a farabrella kinda a diy thing made from faraday fabric weighs about 350gr for a 1m diameter dish. They are available on ebay.
wkat4242•9mo ago
Thanks I'll check it out!
Liftyee•9mo ago
Neat project! I've always wanted to try downlinking data from satellites because it just seems like magic. I wonder what sort of reactions you'd get from setting this up in a backpack/cyberdeck and walking around pointing a satellite dish at the sky.

Am I missing something or is this repo devoid of the code mentioned in the README?

I don't think it's being given away for free sorry about that

benbojangles•9mo ago
what are you trying to say exactly. Can you be more specific?
opello•9mo ago
While I'm not sure it runs afoul of the Show HN rules linked, it may given the referenced repository[1] isn't public. The linked repository from this post[2] and the YouTube video[3] might be sufficient.

But I agree it's a little disappointing to not see the code behind the demo.

I guess I'm just too far down the motion-capture rabbit hole, but I first interpreted this phrase as "tracking hands by satellite" rather than "tracking satellites by hand". I think purely linguistically (without any context that it's going to be easier for a hand to track a satellite than a satellite to track a hand) it's likely to be interpreted that way, also.
